                                <h3>题目描述</h3><p><div>Viruses are usually bad for your health. How about fighting them with... other viruses? In&nbsp;</div>
<div>this problem, you need to find out how to synthesize such good viruses.&nbsp;</div>
<div>We have prepared for you a set of strings of the letters A, G, T and C. They correspond to the&nbsp;</div>
<div>DNA nucleotide sequences of viruses that we want to svnthesize, using the following operations:&nbsp;</div>
<div>* Adding a nucleotide either to the beginning or the end of the existing sequence&nbsp;</div>
<div>* Replicating the sequence, reversing the copied piece, and gluing it either to the beginmng or&nbsp;</div>
<div>to the end of the original (so that e.g., AGTC can become AGTCCTGA or CTGAAGTC).&nbsp;</div>
<div>We're concerned about efficiency, since we have very many such sequences, some of them verv&nbsp;</div>
<div>long. Find a wav to svnthesize them in a mmimum number of operations.&nbsp;</div>
<div>你要用ATGC四个字母用两种操作拼出给定的串：&nbsp;</div>
<div>1.将其中一个字符放在已有串开头或者结尾&nbsp;</div>
<div>2.将已有串复制，然后reverse，再接在已有串的头部或者尾部&nbsp;</div>
<div>一开始已有串为空。求最少操作次数。&nbsp;</div>
<div>len&lt;=100000&nbsp;</div>
<div></div>
<p></p></p><hr/><h3>输入格式</h3><p><div>The first line of input contains the number of test cases T. The descriptions of the test cases&nbsp;</div>
<div>follow:&nbsp;</div>
<div>Each test case consists of a single line containing a non-empty string. The string uses only&nbsp;</div>
<div>the capital letters A, C, G and T and is not longer than 100 000 characters.&nbsp;</div>
<div></div>
<p></p></p><hr/><h3>输出格式</h3><p><div>For each test case, output a single line containing the minimum total number of operations&nbsp;</div>
<div>
<div>necessary to construct the given sequence.</div>
<div></div>
